Studio Reference Amplifier

US PRICE: $1199

800 Watts of Reference-Grade Power.

The Avantone Pro CLA-400 Studio Reference Amplifier is a dynamic, high output, high resolution, full-range system built the old school way; a classically designed Class A/B amplifier. We took particular care to create an amplifier in the traditional studio style, with generous VU meters, high quality Japanese components and a serious toroidal transformer linear power supply. The CLA-400 implements a classic bipolar transistor design for robust bottom end.

In a standard 3U rack mount chassis, this amplifier can generate over 400 watts per channel into an 8 ohm load, making it perfect for medium to large speakers in a studio environment. The CLA-400 not only uses no-compromise components, but is also convection cooled – no fan noise, so it can be used in the same room as the monitors.

The CLA-400 was designed to be paired with the CLA-10 studio monitors, but it can be used with just about any demanding speaker load. Very low distortion, steady performance under harsh conditions, and an open and transparent sound make this an obvious choice for discerning studios requiring serious dynamic range.

Zero Fan Noise

The CLA-400 Studio Reference Amplifier is designed to be used in a studio environment requiring high power output with no fan noise. Under testing, it delivers a powerful 208 watts into 8 ohms and can run at one third power without thermal fault. The CLA-400 has zero fan noise, as it’s convection cooled — which makes it perfectly suited for control room installation.

The CLA Monitor Family — Only from Avantone.

We’ve worked tirelessly to bring this classic monitor system back to the world — but it took more than just recreating a single speaker. A tremendous amount of attention has been put into every detail: matching the original MDF and wood veneer for the cabinet, matching the original winding dimensions/value/dc resistance of the inductors, profiling the most popular amplifier pairings of the original, just to name a few things. All of this development has culminated into a slew of monitor solutions.

The CLA-10 and CLA-10A: the iconic “white cone” monitors, in both passive and active configurations.

The CLA-100 and CLA-200: reference amplifiers with the perfect voicing to compliment the CLA-10 and original “white cones”

AV10 MHF and AV10 MLF: the classic “white cone” drivers — now available for the first time in decades as direct replacements for the original.

AV10 MXO: replacement crossover for original Yamaha™ NS10M™ studio monitors.
